Yes, nasal mucus is awful and deserves a spot on a top-ten list of disgusting bodily substances to find in your Dunkin' Donuts coffee. Still, we can think of nine other such substances that would be even worse.

(And, just to increase the degree of difficulty, we're not even including urine or feces!)

9. Blood
Yes, many cuisines consider congealed blood a foodstuff. As far as we know, though, this isn't congealed human blood. More to the point, blood has a distinct metallic taste that just doesn't jibe with the flavor of coffee.

Top that off for you?

8. Semen
Should semen rank higher? No. First, just wait till you see bodily substances #7 through #1. Second, semen is packed with protein. Finally, it's great for your complexion! No, really, we swear it is!

Oh, we thought you said seamen.

7. Bile
The bitter dregs of a thousand college hangovers. Speaking of which, your average barista is a prime candidate to be ready to produce it at a moment's notice.

5. Chyme
Chyme is the molten stew of partially digested food waiting in your stomach for passage into the depths of your bowels. How terrible is chyme? One of bile's functions is to counteract its acidity.

4. Candida-Vaginitis Discharge
The discharge caused by this yeast infection is often compared to cottage cheese in its appearance. Cottage cheese is a questionable food stuff at best -- and certainly belongs nowhere near your cuppa.

Why is anonymity so important to the Internet? So we can be free to post problems such as this to a medical forum.
